Decision-making is often dependent on uncertain data, e.g. data associated
with confidence scores or probabilities. We present a comparison of different
information presentations for uncertain data and, for the first time, measure
their effects on human decision-making. We show that the use of Natural
Language Generation (NLG) improves decision-making under uncertainty, compared
to state-of-the-art graphical-based representation methods. In a task-based
study with 442 adults, we found that presentations using NLG lead to 24% better
decision-making on average than the graphical presentations, and to 44% better
decision-making when NLG is combined with graphics. We also show that women
achieve significantly better results when presented with NLG output (an 87%
increase on average compared to graphical presentations).

本文比较不同的信息表现形式对人类决策的影响，发现使用自然语言生成（NLG）在不确定情况下可以提高决策水平，在 442 名成年人的任务研究中，NLG 的表现相对于图形表现平均要好 24％，而将 NLG 与图形结合使用可使决策水平提高 44％。同时发现，当使用 NLG 输出时，女性的表现显著优于男性（相对于图形表现增加了 87％）。
